| Outline of Final Research Achievements |
The concept of “one airway, one disease” reflects a comprehensive approach to the treatment of upper and lower airway inflammation. One of the representative diseases for this concept is known as eosinophilic chronic rhinosinusitis (ECRS) combined with asthma. Although little is known about interaction between upper and lower airway inflammation, one of the possibility mechanisms for the observed association between upper and lower airway inflammation exists the nasal-bronchial reflex (NBR). Here, we investigated the relationship between the upper and lower airway, focusing on NBR. We found that airway resistance involved an interaction between the upper and lower airways via the cholinergic nerve and this response during allergic airway inflammation was higher than that of the negative controls. Thus, understanding the relationship between the upper and lower airways in the context of NBR sheds light on novel therapeutic strategies for ECRS accompanied by asthma.
